Cornyn, who made public the letter from Nabors on Friday, said
that in response he re-released a hold that he had placed on the nomination of
Mark Lippert as assistant secretary of Defense for Asian and Pacific security
affairs.

While the Nabors letter does not get into details about when
a sale might occur or how many fighters could be involved, it will add to a
growing list of tensions between Washington and Beijing as Geithner and
Clinton prepare to visit China for this year’s U.S.-China Strategic &
Economic Dialogue.

The case of Chinese human-rights activist Chen Guangcheng,
who escaped from house arrest and reports say has sought refuge in the American Embassy in Beijing, has threatened to hijack the U.S.-China meeting.
Geithner and Clinton are not canceling the trip, however, Bloomberg reported
Sunday.

Selling arms to Taiwan has long been a point of contention between
the United States and China. In selling the Taiwanese F-16 fighters, Nabors said, “we
recognize that China has 2,300 operational combat aircraft, while our
democratic partner Taiwan has only 490.”

He said that Lippert would play a lead role as the
administration decides “a near-term course of action on how to address Taiwan's
fighter gap, including through the sale to Taiwan of an undetermined number of
new U.S.-made fighter aircraft.”

National Security Council spokesman Tommy Vietor said that
the letter to Cornyn “is consistent with our current policy on Taiwan, which has
not changed.”

“We do not comment on future possible foreign military sales
unless formal congressional notification has taken place,” Vietor said in an
email.
